Hey guys I'm hoping someone on this site can give me a bit of insight on a 2003 wiper motor.
I'm converting it fof a hot rod project and would like to know how to hook up the wires to get this thing just to run. There's 4 wires coming out (black,orange,green,blue) and I'm assuming the body is the ground itself. I would like to disconnect the little black box with the circuit board and just run the main wires directly. Any help would be appreciated, thanks

 

Are the 4 wire colors you reference from the motor itself, or from the truck to the box on the motor assembly? The colors you mention do not align with the wiring diagram so I'm suspecting those are of the motor itself....

Yes those wires are directly from the motor. And I forgot to mention it's a 03 explorer

 

Unfortunately I don't find anything specific to the motor used on the liftgate wiper motor for a 2003 Explorer. Since it has 4 wires and the motor is a 2-speed motor, I'd have to assume that one wire is the Park/Run wire, one is low speed, one is high speed, and one is ground. The ground wire would likely have continuity to the motor case and/or wiper shaft. The Park/Run wire probably is open circuit to currently, the Low speed will have some amount of resistance to the ground terminal as will the high speed. I'd expect that the high speed wire will have lower resistance to ground than the low speed, but those will be easy enough to figure out once you're bench testing it.

Ok thanks. Guess I'll just start tapping wires together

 

So I got half the battle beat.ive got black grounded and orange at 12v and it's running on the slow setting, nothing else though. Any idea on for getting the high speed going? I tried jumping a couple wires with it but nothing happens.

 

Have you checked for continuity to the motor case from the black wire as well as the orange wire to see which has the lowest resistance? If the orange wire, that might be the ground wire. It's not always safe to assume in cars that black wires are ground.

Yes , actually both orange and black had continuity to the body, which I thought was really odd

 

I would expect three to have low resistance to the body, but only one to be essentially a dead short. The other two would have slightly higher resistance through the windings for the low speed winding and high speed winding.

That's what I was thinking too. I did some more messing around though and found that the blue is the constant 12v. When I jump green to blue it's park, and orange to blue is swipe. Black is definitely ground.
Starting to think though maybe it's not 2 speed.

 

I'm curious what you mean by "green to blue it's park." The Constant 12V should be for the park feature, which applies power to the motor long enough to find the park position once the switch is turned off. That makes me wonder of the function that you suspect is "swipe" is actually triggering the Park function.

Yea I'm pretty confused by the whole thing now. Multimeter doesn't Jive with anything that makes sense either.
What I've got is this.
Black is ground
If I hook power to green or blue it's nothing on its own, but if i jump another wire from the orange to which ever wire I have power to it swipes.
If I then connect orange to the other wire (blue or green, which ever hasn't got power to it) it then parks.
Tried every combo I can think and can't get a second speed going

 

Do you have a multimeter that you can use to provide high accuracy resistance (ohm) measurements from each of the wires to the motor/gear box housing? That may help identify which wire should be what.

Did you happen to note the direction of motor rotation for each of the combinations? Were they all the same, or did maybe one or two result in the motor spinning the opposite direction?

When you say "swipes" do you mean the motor continues to run, or only makes a single swipe and stops?
